Any tutorial available on QScintilla + C++?

Hi,
I got to know that QScintilla is a powerful tool developed for Text highlighting, syntax styling, error indicator,.....etc.. I wanted to use this in my Qt based GUI but I am not getting any tutorial to start with. Please let know if there is any tutorial is available for the same.
Also let me know if any problem/challenges so far you have observed in using QScintilla with CPP.
